More Details on Our Top Picks

  1. Greenworks 80V 21 in Self-Propelled Lawn Mower with 4.0 Ah Battery and Charger

    Greenworks 80V 21 in Self-Propelled Lawn Mower with 4.0 Ah Battery and Charger

    Best Overall Electric Self-Propelled Mower

    View Latest Price

    This Greenworks model stands out for combining high power with user-friendly features, making it a top choice for those seeking an electric mower that can handle medium-sized lawns efficiently. Its 80V brushless motor delivers strong cutting performance, comparable to some gas options like the SENIX 22” with a 170cc engine, but without the maintenance hassle. The self-propelled rear-wheel drive with variable speed simplifies maneuvering, especially on uneven terrain. The inclusion of LED headlights extends mowing time into early mornings or late evenings, adding convenience. However, the battery life, roughly half an acre per charge, may be limiting for larger yards, and the weight could be an issue for some users. Compared with the Greenworks 40V model, this offers more power but at a higher cost and heavier weight. It’s ideal for homeowners who want quiet operation, low maintenance, and a versatile system.

    Pros:
    • Powerful 80V battery for efficient mowing
    • Self-propelled with variable speed for easy control
    • Includes LED headlights for early morning or evening use
    • Versatile 4-in-1 system for mulching, bagging, side discharge, and leaf pickup
    Cons:
    • Battery life may vary depending on grass and user technique
    • Potentially heavy for some users when fully assembled
    • Limited to approximately half an acre per charge

    Best for: Homeowners with medium-sized lawns who prefer electric power and minimal upkeep.

    Not ideal for: Large property owners or those with very thick, tall grass that requires extended runtime and maximum power.

    • Voltage:80V
    • Cutting Width:21 inches
    • Battery Capacity:4.0 Ah
    • Motor Type:Brushless
    • Deck Material:Steel
    • Features:Self-propelled, LED headlights, 4-in-1 system
    Our verdict
    “This model suits homeowners seeking a powerful, quiet electric mower with versatile features for medium lawns.”
  2. Greenworks 80V 21″ Brushless Cordless Self-Propelled Lawn Mower with 4.0Ah Battery and Rapid Charger

    Greenworks 80V 21" Brushless Cordless Self-Propelled Lawn Mower with 4.0Ah Battery and Rapid Charger

    Best Long Runtime Cordless Electric Mower

    View Latest Price

    This Greenworks cordless mower emphasizes long runtime and minimal maintenance, making it a solid pick for users prioritizing convenience over gasoline. Its 80V brushless motor offers similar power to the B0CLSC6B2T, yet its smart technology, dubbed ‘SmartCut,’ adjusts power dynamically, which can prolong battery life during lighter cuts—compared to the more straightforward operation of the Greenworks 40V model. The 21-inch steel deck and self-propelled rear-wheel drive facilitate easy handling, especially with multiple height adjustments (7 positions). The runtime of up to 45 minutes beats many gas models, but it may still be insufficient for larger yards, especially if the grass is thick. Pricewise, it leans toward the higher end, but the quick 60-minute charger boosts usability. This mower is well-suited for tech-savvy homeowners who value quiet, eco-friendly operation and quick turnaround.

    Pros:
    • Powerful 80V brushless motor with adaptive ‘SmartCut’ technology
    • Up to 45 minutes of runtime, suitable for medium yards
    • Self-propelled with 7-position height adjustments
    • Fast 60-minute rapid charger reduces downtime
    Cons:
    • Run time may be inconsistent depending on grass density and use
    • Price may be higher compared to basic electric mowers
    • Limited to approximately 45 minutes, which could be restrictive for larger lawns

    Best for: Tech-oriented homeowners with medium-sized lawns seeking a low-maintenance, cordless option with decent runtime.

    Not ideal for: Large properties or owners with very thick grass, where runtime could fall short of needs.

    • Voltage:80V
    • Cutting Width:21 inches
    • Battery:4.0 Ah
    • Run Time:up to 45 minutes
    • Charger:60-minute rapid charger
    • Height Adjustment:7 positions
    Our verdict
    “Ideal for tech-savvy homeowners who want a quiet, efficient cordless mower with quick charging and good runtime for medium yards.”
  3. PowerSmart 21″ Gas Self-Propelled Lawn Mower with 170cc OHV Engine, 3-in-1 Mulching/Bagging/Discharge, 6-Position Height, Alloy Steel Deck, Easy Start, Rear-Wheel Drive

    PowerSmart 21" Gas Self-Propelled Lawn Mower with 170cc OHV Engine, 3-in-1 Mulching/Bagging/Discharge, 6-Position Height, Alloy Steel Deck, Easy Start, Rear-Wheel Drive

    Best Gas-Powered Self-Propelled Mower for Hills

    View Latest Price

    This PowerSmart model earns its spot by combining reliable power with affordability, making it a strong choice for medium yards with challenging terrain. Its 170cc OHV engine provides steady, robust performance comparable to the SENIX 22” with a 170cc engine, but with the added benefit of easy start technology. Its rear-wheel drive and large wheels facilitate handling on hills and uneven ground, which less capable models like the PowerSmart 21-inch gas mower might struggle with. The 3-in-1 functionality, quick height adjustments, and alloy steel deck ensure durability and versatility. A notable tradeoff is the blade size—at 20 inches—meaning you’ll need to replace blades more frequently or order specifically. It’s best for homeowners with varied terrain who want a dependable, easy-to-start gas mower.

    Pros:
    • Reliable 170cc engine with easy start technology
    • Self-propelled rear-wheel drive for handling hills
    • Versatile 3-in-1 system for mulching, bagging, and discharge
    • Durable alloy steel deck for long-lasting use
    Cons:
    • Blade size limited to 20 inches, may require specific replacements
    • Handle may need adjustment for taller users
    • Designed primarily for medium-sized yards, not large properties

    Best for: Homeowners with hilly or uneven yards seeking a reliable, gas-powered mower with versatile features.

    Not ideal for: Owners with flat, small lawns who prefer electric or lighter mowers for ease of use.

    • Engine:170cc OHV
    • Cutting Width:21 inches
    • Deck Material:Alloy Steel
    • Height Adjustment:6 positions (1.5″–3.9″)
    • Drive:Rear-wheel drive
    • Wheels:10-inch large wheels
    Our verdict
    “A dependable choice for homeowners with sloped and uneven lawns who want a gas mower with versatile cutting options.”
  4. SENIX 22” Self Propelled Gas Lawn Mower, 170cc 4-Cycle Engine, 3-in-1 (Bagging/Mulching/Side Discharge), Adjustable Height

    SENIX 22'' Self Propelled Gas Lawn Mower, 170cc 4-Cycle Engine, 3-in-1 (Bagging/Mulching/Side Discharge), Adjustable Height

    Best for Large Yards with Heavy Grass

    View Latest Price

    The SENIX 22” stands out for its larger cutting width and powerful 170cc engine, making it well-suited for larger yards or thicker grass than smaller models like the PowerSmart 21-inch. Its 4-cycle engine delivers reliable, consistent power, and the rear-wheel drive simplifies handling on uneven terrain. The 3-in-1 functionality offers flexibility, and the 6-position height adjustment helps tailor the cut to your lawn’s needs. While its larger size and sturdy steel deck enhance durability, it may be more cumbersome for storage and maneuvering in tight spaces. The absence of specific weight data leaves some uncertainty about ease of use for less experienced users. Overall, this mower offers substantial power for demanding lawns but is less suitable for small, flat yards.

    Pros:
    • Larger 22-inch cutting width for efficient coverage
    • Powerful 170cc 4-cycle engine for heavy grass
    • Versatile 3-in-1 system with quick mode switching
    • Adjustable height for customized mowing
    Cons:
    • Potentially bulky and heavier for some users
    • No specific weight info, which could affect maneuverability
    • Designed for larger yards, less ideal for small spaces

    Best for: Homeowners with large, thick, or uneven lawns who need a robust gas mower with wide cutting capacity.

    Not ideal for: Small or flat yard owners seeking lightweight, easy-to-store electric options.

    • Engine:170cc 4-cycle
    • Cutting Width:22 inches
    • Deck Material:Steel
    • Height Adjustment:6 positions (1.25″–4″)
    • Drive:Rear-wheel drive
    • Warranty:2 years
    Our verdict
    “Best suited for large properties or thick grass that demand a powerful, wide-cut gas mower with versatility.”
  5. PowerSmart 21-inch Self-Propelled Gas Lawn Mower with 170cc OHV Engine

    PowerSmart 21-inch Self-Propelled Gas Lawn Mower with 170cc OHV Engine

    Best Overall for Power and Versatility

    View Latest Price

    This model stands out for its reliable 170cc engine and wide 21-inch cutting deck, making it a strong choice for those with medium to large yards who need efficiency and power. Compared with the YARDMAX 22-inch model, it offers slightly less advanced traction features but provides a more straightforward, robust gas engine. Its 3-in-1 system allows for flexible lawn care, and adjustable heights mean you can tailor the cut to your yard’s needs. However, its weight could be a challenge for some users, and the absence of an electric start may lead to more effort during startup. Still, for those seeking a dependable, versatile gas mower that handles larger areas with ease, this pick delivers solid performance.

    Pros:
    • Powerful 170cc engine for consistent performance
    • Wide 21-inch deck for efficient mowing
    • Versatile 3-in-1 system: bagging, mulching, discharge
    Cons:
    • Can be heavy, making it harder to maneuver for some users
    • No electric start feature, requiring manual pull-starting

    Best for: Homeowners with medium to large yards who prioritize power and versatile cutting options

    Not ideal for: Users seeking a lightweight, electric, or quieter mower for small or noise-sensitive yards

    • Engine:170cc OHV
    • Cutting Width:21 inches
    • Cutting Heights:1.5 to 3.9 inches
    • Bag Capacity:1.4 bushels
    • Drive Type:Self-propelled rear-wheel drive
    • Wheels:10-inch rear wheels
    • Deck Material:Steel
    • Suitable Yard Size:Medium
    Our verdict
    “This gas mower is ideal for users who need reliable power and efficiency on larger lawns but are comfortable with its weight and manual start process.”
  6. YARDMAX 22 in. 201cc Select PACE 6 Speed CVT Gas Walk Behind Lawn Mower, Black (YG2860)

    YARDMAX 22 in. 201cc Select PACE 6 Speed CVT Gas Walk Behind Lawn Mower, Black (YG2860)

    Best for Smooth Speed Control and Traction

    View Latest Price

    The YARDMAX YG2860 offers a standout feature: a CVT transmission with 6 adjustable speeds, providing smooth, customizable control that surpasses traditional gear-driven mowers like the SENIX 21”. This makes it especially suitable for users who want precise speed management on varied terrain. Its spiked tread tires improve traction, making it a better fit for sloped or uneven lawns. The automatic choke simplifies starting, and the deck cleanout port reduces maintenance hassle. On the downside, it tends to be heavier, which could be a drawback for less experienced users or those with limited strength. Compared to electric options like the EGO, it offers more power but at the cost of noise and emissions. This mower is a good choice for those who value control and traction over weight and noise.

    Pros:
    • Smooth, adjustable CVT transmission for precise speed control
    • Enhanced traction with spiked tread tires
    • Easy starting with automatic choke system
    Cons:
    • Heavier than comparable models, may tire some users
    • Limited to gas operation, with maintenance needs

    Best for: Gardeners needing adjustable speed and enhanced traction on varied terrain

    Not ideal for: Users looking for a lightweight or electric mower for small yards with minimal slopes

    • Cutting Width:22 inches
    • Engine Displacement:201cc
    • Transmission:CVT with 6 speeds
    • Tire Type:Rubber with spiked tread
    • Features:Automatic choke, deck cleanout port
    • Suitable Yard Size:Medium to large
    Our verdict
    “Ideal for users who want customizable speed and superior traction, especially on uneven or hilly lawns, despite added weight.”
  7. PowerSmart 21-Inch Self Propelled Gas Lawn Mower with 170cc OHV Engine

    PowerSmart 21-Inch Self Propelled Gas Lawn Mower with 170cc OHV Engine

    Best for Compact Storage and Basic Power

    View Latest Price

    This PowerSmart model emphasizes convenience, with a foldable handle that makes storage easier. Its 170cc engine offers dependable power, similar to the other gas options, but this model sticks to standard rear-wheel drive, which works well on flat or gently sloped lawns. The 3-in-1 functionality makes it versatile for different lawn conditions, and the adjustable heights provide some customization. However, it lacks advanced speed control or traction enhancements, making it less suitable for hilly terrains or larger, complex yards. The weight and noise level are typical for gas mowers, which might be a concern for some. Overall, this mower suits users who prioritize straightforward operation and space-saving storage over advanced features or maneuverability on slopes.

    Pros:
    • Powerful 170cc engine for consistent cutting
    • Foldable handle for compact storage
    • 3-in-1 system for mulching, discharge, and bagging
    Cons:
    • Lacks adjustable speed settings for varied terrain
    • Potentially heavy and noisy during operation

    Best for: Homeowners needing a reliable, straightforward gas mower with easy storage

    Not ideal for: Users with hilly terrain or large, complex landscapes requiring advanced traction or speed control

    • Engine:170cc OHV
    • Drive:Rear-wheel drive
    • Deck Material:Steel
    • Cutting Width:21 inches
    • Cutting Height:1.5 to 3.9 inches
    • Features:3-in-1 (mulching, side discharge, rear bagging), foldable handle
    Our verdict
    “Best suited for small to medium yards where straightforward, space-saving mowing is a priority, not for complex terrain or hills.”
  8. SENIX 21” Self Propelled Gas Lawn Mower 170 cc 3-in-1, 6-Position Cutting

    SENIX 21'' Self Propelled Gas Lawn Mower 170 cc 3-in-1, 6-Position Cutting

    Best for Precise Control and Modest Yards

    View Latest Price

    The SENIX 21” model delivers a strong 170cc engine with low vibration, making it a good choice for users who value smooth operation. Its six-position height adjustment allows for detailed customization, and the 3-in-1 system offers versatility comparable to higher-end models like the YARDMAX. Designed for yards up to 1/3-acre, it excels on flat terrain, but may struggle on steep slopes or uneven ground. Its weight can be a concern for those who prefer lighter machines, and its size makes storage or transport slightly less convenient. Compared with electric models like the EGO, it provides more power but at the expense of noise and emissions. This mower is well suited for homeowners with smaller, flat lawns seeking reliable, adjustable cutting performance.

    Pros:
    • Powerful 170cc engine with low vibration
    • Six-position height adjustment for precise control
    • Versatile 3-in-1 cutting system
    Cons:
    • Heavy for some users, especially during lifting or transport
    • Limited performance on steep terrain

    Best for: Homeowners with flat, modest-sized lawns who want a dependable, adjustable gas mower

    Not ideal for: Those with large or hilly yards, or who prefer electric, quieter options

    • Cutting Width:21 inches
    • Engine:170 cc 4-cycle OHV
    • Horsepower:3.8 HP
    • Torque:6.5 ft-lb
    • Deck Material:Steel
    • Bag Capacity:1.7 bushels
    • Height Adjustment:6 positions (1.25 to 3.75 inches)
    • Wheels:8-inch front, 11-inch rear
    Our verdict
    “This mower suits owners of flat, small to medium lawns needing adjustable, reliable power without extra frills.”
  9. EGO 21-Inch Self-Propelled Mower with Dual Toggle Kit (6.0Ah, 320W Charger)

    EGO 21-Inch Self-Propelled Mower with Dual Toggle Kit (6.0Ah, 320W Charger)

    Best for Quiet, Eco-Friendly Power

    View Latest Price

    The EGO 21-inch electric mower offers a quiet, emission-free alternative to gas models like the PowerSmart and SENIX. Its 6.0Ah battery provides up to 50 minutes of runtime, making it suitable for small to medium yards where noise and fumes are concerns. Its multiple height adjustments and 3-in-1 functionality match the versatility found in gas options, with added convenience like LED headlights for early morning or late evening mowing. However, its power may not match the raw torque of gas engines, especially on thick or tall grass, and the weight of battery packs can add to handling challenges. Compared to gas models, this mower excels in quieter operation and lower maintenance, making it ideal for eco-conscious homeowners with smaller lawns who prioritize quiet, clean power.

    Pros:
    • Long runtime of up to 50 minutes with a powerful 6.0Ah battery
    • Versatile 3-in-1 functions including mulching and side discharge
    • Quiet operation with no emissions
    Cons:
    • Limited power compared to gas models, potentially less effective on thick grass
    • Weight of battery packs can be cumbersome for some users

    Best for: Homeowners seeking a quiet, low-maintenance mower for small to medium yards

    Not ideal for: Large yards or thick, tall grass where maximum power is needed

    • Cutting Width:21 inches
    • Battery:6.0Ah ARC Lithium
    • Charger:320W
    • Run Time:Up to 50 minutes
    • Cutting Height:1.25 to 4 inches

    View Latest Price

    This model stands out for its robust 170cc engine, making it a top choice for tackling thick, overgrown lawns with ease. Compared with the Greenworks 48V and 60V models, its gas engine provides more consistent power for heavy-duty jobs, but it also means the mower is heavier and noisier. The 7 adjustable height settings and versatile 3-in-1 system give it a tailored cut for various lawn conditions, though its manual pull start might be less convenient than electric alternatives. Its steel deck ensures durability, but the weight could limit maneuverability for some users. Overall, this mower suits homeowners needing reliable, high-power performance for medium-sized, challenging yards, but those seeking quiet and lightweight operation should consider electric options.

    Pros:
    • Powerful 170cc engine handles tough, thick grass
    • Versatile 3-in-1 system for mulching, bagging, and side discharge
    • Adjustable height settings for customized mowing
    Cons:
    • Heavy and potentially difficult to maneuver for some users
    • Manual pull start may be less convenient than electric start
    • Potentially noisy due to gas engine

    Best for: Homeowners with medium to large lawns that include thick or overgrown grass requiring robust power.

    Not ideal for: Users prioritizing quiet operation or seeking a lightweight, easy-to-maneuver mower for small or flat lawns.

    • Engine:170cc 4-cycle OHV
    • Cutting Width:21 inches
    • Cutting Height Adjustment:7 positions from 1 to 3 inches
    • Grass Bag Capacity:1.9 bushels
    • Deck Material:Steel
    • Cutting System:3-in-1 (mulching, bagging, side discharge)
    Our verdict
    “This mower is best suited for those who need serious power and durability for medium-sized, challenging lawns and don’t mind the extra weight and noise.”
  11. Greenworks 40V 21-inch Brushless Cordless Self-Propelled Lawn Mower with 5.0Ah Battery and Charger

    Greenworks 40V 21-inch Brushless Cordless Self-Propelled Lawn Mower with 5.0Ah Battery and Charger

    Best Quiet Electric Self-Propelled Mower

    View Latest Price

    This mower offers a quieter, cleaner alternative to gas models like the PowerSmart 21-inch, thanks to its brushless motor and 40V battery. Its self-propelled rear-wheel drive makes mowing on uneven terrain easier and less tiring, while the 7-height adjustments and 3-in-1 system provide flexibility for different lawns. Compared with the Greenworks 48V version, this 40V model may have slightly less power but still delivers smooth, reliable performance for small to medium yards. The vertical storage feature adds convenience, but runtime can vary significantly depending on grass thickness and operator technique, which might make it less suitable for large, heavily overgrown lawns. This pick is ideal for homeowners seeking a quiet, eco-friendly mower for regular maintenance of manageable lawns.

    Pros:
    • Quiet operation with brushless motor
    • Self-propelled rear-wheel drive for easier handling
    • Vertical storage for space-saving storage
    Cons:
    • Runtime may be limited on larger or thick lawns
    • Battery life depends on grass and mowing conditions
    • Handle may lack foldability for compact storage

    Best for: Homeowners with small to medium-sized lawns seeking a quiet, low-maintenance electric mower.

    Not ideal for: Lawn owners with very large or overgrown yards, where battery runtime may be insufficient for extended sessions.

    • Voltage:40V
    • Cutting Width:21 inches
    • Battery:5.0Ah included
    • Runtime:Up to 45 minutes
    • Deck Material:Steel
    • Height Adjustment:7 positions
    Our verdict
    “This mower is perfect for users prioritizing quiet, eco-friendly operation on small to medium lawns and willing to accept some runtime limitations.”
  12. SENIX X6 60V Max 21-Inch 3-in-1 Self-Propelled Mower with 8Ah Battery & Charger

    SENIX X6 60V Max 21-Inch 3-in-1 Self-Propelled Mower with 8Ah Battery & Charger

    Best High-Performance Battery-Powered Mower with Smart Features

    View Latest Price

    The SENIX X6 makes a compelling case for those needing extended runtime and smart features, outperforming many electric rivals like Greenworks 60V with its 8Ah battery offering up to 60 minutes of operation. Its 60V brushless motor delivers strong cutting power, and the 3-in-1 system ensures versatility across different lawn conditions. The smart display adds convenience, providing real-time feedback on battery status and performance, a feature absent in simpler models. However, the mower and battery ship separately, which could delay setup, and its assembly may be a hurdle for some users. Compared to the Greenworks 48V or 40V models, the SENIX X6 is better suited for larger yards where long runtime and advanced features justify the higher price and setup effort.

    Pros:
    • Long runtime up to 60 minutes with 8Ah battery
    • Powerful 60V brushless motor
    • Smart display for real-time feedback and control
    • Versatile 3-in-1 system
    Cons:
    • Mower and battery ship separately, delaying use
    • Requires assembly, which could be challenging
    • Higher price point compared to basic models

    Best for: Homeowners with large yards seeking maximum runtime, smart features, and high power for efficient lawn care.

    Not ideal for: Users who prefer plug-and-play simplicity or have small, easily manageable lawns, as setup and cost might be overkill.

    • Voltage:60V
    • Cutting Width:21 inches
    • Battery Capacity:8.0Ah
    • Runtime:Up to 60 minutes
    • Features:Smart display, 3-in-1 (mulching, bagging, side discharge), self-propelled
    • Warranty:5-year limited tool, 3-year battery/charger
    Our verdict
    “This mower is ideal for tech-savvy homeowners with large lawns who want extended runtime and smart features, accepting the setup complexity.”
  13. Greenworks 48V 21-inch Self-Propelled Lawn Mower, (2) 5.0 Ah Battery Kit

    Greenworks 48V 21-inch Self-Propelled Lawn Mower, (2) 5.0 Ah Battery Kit

    Best Versatile Battery System with Dual Batteries

    View Latest Price

    This Greenworks model offers a strong balance between power and runtime, especially with its two 5.0 Ah batteries, making it well-suited for larger or more demanding lawns than single-battery models like the 40V. Its 48V brushless motor ensures quiet, durable operation, while the variable speed control lets me match mowing pace to terrain. The 4-in-1 system provides flexibility, and the self-propelled rear-wheel drive makes controlling the mower easier on uneven ground. Compared to the 60V Greenworks, it might deliver slightly less raw power but benefits from longer battery life and efficient energy use. Its heavier weight can be a drawback for some users, especially those with smaller or flatter lawns, and battery recharge time isn’t specified, which could impact ongoing work.

    Pros:
    • Two 5.0 Ah batteries for extended runtime
    • Versatile 4-in-1 system for multiple mowing needs
    • Variable speed control for tailored operation
    • Quiet, brushless motor for durability
    Cons:
    • Heavier weight than some electric models
    • Recharge time for batteries not specified
    • Runtime may vary depending on grass and terrain

    Best for: Homeowners needing extended runtime and versatility for larger yards with varied terrain, willing to handle a heavier mower.

    Not ideal for: Users with small, flat lawns seeking a lightweight, easy-to-maneuver electric mower, as weight might be a concern.

    • Battery Voltage:48V
    • Battery Capacity:2 x 5.0 Ah
    • Cutting Width:21 inches
    • Run-Time:Up to 45 minutes
    • Features:Self-propelled, variable speed, 4-in-1 system
    Our verdict
    “This mower offers ample power and runtime for larger, varied lawns, especially when extended mowing sessions are needed, despite some added weight.”
  14. Greenworks 60V 21-inch Self-Propelled Lawn Mower with (2) 4.0 Ah Batteries

    Greenworks 60V 21-inch Self-Propelled Lawn Mower with (2) 4.0 Ah Batteries

    Best for Large Yards with Versatile Battery Power

    View Latest Price

    This Greenworks 60V model excels for large yards, thanks to its dual 4.0 Ah batteries, providing enough energy for extended mowing sessions with minimal downtime. Its brushless motor delivers quiet, efficient power, and the 4-in-1 system supports mulching, bagging, side discharge, and leaf pickup, making it adaptable for seasonal needs. The inclusion of LED headlights adds visibility for early mornings or late evenings, a feature absent in many competitors like the PowerSmart gas models. However, performance may vary based on terrain and grass density, and the mower’s weight can be substantial for some users. Overall, this mower makes a strong case for those with sizable properties who want quiet operation combined with versatile mowing options and extended battery life.

    Pros:
    • Powerful 60V brushless motor suitable for large yards
    • Two batteries for extended runtime
    • 4-in-1 system including leaf pickup
    • LED headlights for improved visibility
    Cons:
    • Performance may depend on terrain and grass density
    • Heavier than manual push mowers
    • Price may be higher with multiple batteries included

    Best for: Homeowners with large, varied yards needing a quiet, eco-friendly, feature-rich mower with ample runtime.

    Not ideal for: Those with smaller, flat lawns or limited storage space may find it too heavy or feature-rich for their needs.

    • Voltage:60V
    • Batteries:2 x 4.0 Ah
    • Cutting Width:21 inches
    • Warranty:4 years tool + 4 years battery
    • Features:Self-propelled, LED headlights, 4-in-1 options
    Our verdict
    “This mower is ideal for large properties where quiet, versatile, and long-lasting battery power is a priority, accepting the added weight and cost.

The products in this roundup were selected based on a combination of performance, ease of use, build quality, and value. We prioritized models that offer reliable self-propulsion, key safety features, and user-friendly controls. Battery-powered options were evaluated for runtime, charging speed, and compatibility with other tools, while gas models were assessed for engine reliability, maintenance requirements, and cutting performance.

Our ranking reflects a balanced view of affordability, durability, and suitability for different yard sizes and user preferences.

Factors to Consider When Choosing Best Self-propelled Lawn Mowers

When choosing the best self-propelled lawn mower, it’s important to consider factors beyond just power and price. Think about your yard’s size, terrain, and how much effort you’re willing to put into maintenance. Features like adjustable height settings can improve mowing precision, while battery capacity influences runtime. Knowing whether you prefer electric or gas power can impact ongoing costs and convenience. Paying attention to durability and warranty coverage can also save headaches down the line. This guide explores key considerations to help you make an informed decision tailored to your needs.

Yard Size and Terrain

The size and terrain of your yard directly influence the type of mower you should choose. Larger lawns benefit from gas models with longer run times, while smaller or flat yards are well-suited to electric options that offer quieter operation and less maintenance. Steep slopes or uneven ground may require models with enhanced traction and stability features. Ignoring these factors can lead to frustration or frequent recharging, so match your mower’s capabilities with your yard’s demands for best results.

Power Source and Runtime

Electric models vary widely in battery capacity, which affects how long you can mow before needing a recharge. Higher voltage batteries (like 60V or 80V) typically deliver more power and longer runtime, ideal for larger yards. Conversely, lower voltage batteries are lighter and easier to handle but may require more frequent recharging. Gas models, with their continuous fuel source, generally offer unlimited runtime but involve more upkeep and emissions. Consider your typical mowing session length and convenience preferences when selecting the power source.

Cutting and Mulching Features

Multiple cutting height options and 3-in-1 functions—mulching, bagging, side discharge—add versatility to your mowing routine. These features allow for better grass control and yard health, but they can also increase the mower’s complexity and cost. Ensure the mower’s adjustments are straightforward and suited to your grass type and lawn care goals. Overdoing features you don’t need can inflate the price unnecessarily, so prioritize those that align with your mowing habits.

Ease of Use and Maintenance

Look for models with ergonomic handles, simple controls, and easy-to-access components for routine maintenance. Cordless electric mowers generally require less upkeep, with no oil changes or spark plug replacements, whereas gas models demand regular tune-ups. Battery removal and charging should be hassle-free, especially if you plan to store batteries indoors or swap between tools. Balancing ease of use with durability ensures your mower remains reliable over time without frequent repairs.

Budget and Long-Term Value

While lower-priced models may seem appealing initially, they often compromise on durability or features. Investing in a higher-quality mower can save money and hassle in the long run through fewer repairs and better performance. Consider warranties, brand reputation, and included accessories as part of the overall value. Remember, a more expensive mower with superior build quality can be a worthwhile choice if it suits your yard size and mowing frequency.

Frequently Asked Questions

Is a cordless electric self-propelled mower powerful enough for thick or tall grass?

Cordless electric mowers have improved significantly, with many now capable of handling thick or tall grass, especially those with 60V or higher batteries. However, they may still struggle with very dense or overgrown lawns compared to gas-powered models. For regular maintenance of a standard yard, electric options provide enough power and the added benefits of quiet operation and lower emissions. If your yard has particularly tough terrain or overgrown areas, a gas mower might be more dependable for consistent performance.

How often do I need to replace or charge the batteries in an electric self-propelled mower?

The frequency depends on your mower’s battery capacity and your yard size. Larger batteries, like 60V or 80V, generally provide longer runtime per charge, reducing the need for frequent recharges. Smaller batteries might require recharging after each mowing session, especially on larger lawns. Most modern batteries are designed for hundreds of charge cycles, so replacement is infrequent if properly maintained. To maximize lifespan, follow manufacturer instructions on charging and storage, and consider spare batteries if you have a large yard or multiple tools.

Are gas-powered self-propelled mowers more durable than electric ones?

Gas-powered mowers often have a reputation for durability because they are built with robust engines designed for heavy-duty use. They can handle larger, more rugged yards and are less affected by battery limitations. However, they require more maintenance, such as oil changes, spark plug replacements, and periodic tune-ups. Electric models, while generally less durable in extreme conditions, benefit from fewer moving parts and lower maintenance needs. The choice depends on your yard size, maintenance willingness, and budget for upkeep.

What safety features should I look for in a self-propelled lawn mower?

Safety features are essential for preventing accidents during operation. Look for models with blade engagement controls that require deliberate activation, such as a safety handle or switch. Automatic shut-off features when the user releases the handle can prevent accidental injuries. Some mowers include safety shields or covers around the blades to reduce the risk of contact. Checking for sturdy, non-slip wheels and stable handles also improves safety during use. Prioritizing these features can help ensure a safer mowing experience, especially for households with children or pets.

Conclusion

For those seeking an all-around reliable choice, the Greenworks 80V 21 in Self-Propelled Lawn Mower makes a compelling pick thanks to its balance of power, convenience, and value. Budget-conscious homeowners will appreciate the lower-cost electric models like the Greenworks 40V or PowerSmart options that still deliver decent performance. Premium buyers aiming for durability and top features should consider gas-powered options like the SENIX 22-Inch 201cc mower, which handles larger yards with ease. For beginners or those with small, flat lawns, lightweight electric models with simple controls are ideal, offering ease of use without sacrificing quality. Ultimately, your choice depends on yard size, terrain, and how much maintenance you’re willing to handle.
